LOCK.

Specification of Letters Patent.

Patented Aug. 9, 1921.

To allee/01net may concern Be it known that I, MICHAEL MARINO, a citizen of the United States, residing at New York city, in the county of lSew York and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to locks of the type known as mortise locks and has for its principal object to provide a lock which is equally well adapted for both swinging and sliding doors.

Another object is to provide a lock having a bolt which interlocks with the keeper so that an unauthorized person cannot, without the use of a proper key, operate the bolt and gain access to the premises.

Vith these and other objects in view, the invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following description and dra-wings in which,

Figure 1 is a vertical sectional view of my invention showing the bolt disengaged.

Fig. 2 is a similar view showing the bolt in its locking position.

Fig. 3 is a top plan view of the latch'mechanism.

Fig. l is a top plan view of the bolt.

Fig. 5 is a side elevational view of a tumbler.

Fig. 6 is a side elevational view of the bolt operating bar.

Fig. 7 is a side elevational view of another tumbler.

Fig. 8 is a sectional view of the bolt operating knob.

Fig. 9 is a plan view of the same.

Fig. 10 is a vertical sectional view of a modified form of my invention.

Fig. 11 is a similar view showing the bolt disengaged.

Fig. 12 is a side elevational view of the main bolt as illustrated in Figs. 10` and 11.

Fig. 18 is a side elevational view of a secondary bolt illustrated in Figs. 10 and 11.

Fig. 14 is a side elevational view of the keeper, and

Fig. 15 is a side elevational. view of the tumbler employed in Figs. 10 and 11.

My invention comprises a casing 1 which is provided with suitable guides 2 between which a sliding bar 3 moves backward and forward. This bar is provided with recesses e in which .a lug 5 on .a tumbler falls to arrest the bar in either its forward or rear position. rThis lug just described is clearly shown in Fig. 5.

rEhe opposite edge of the sliding bar 3 is provided with a notch .7 for the reception of a key from the outside by which the sliding bar is operated. ln the same edge and in advance of the notch just described 1 provide a second notch 8 forming an abutment for the extension 9 provided on the head 12 of a knob employed on the inside of the lock for operating the same from within. rThis knob, indicated at l() on the drawing is clearly illustrated in Figs. 8 and 9 and consists of a. hollow spindle having a screw 11 passing through the same for detachably securing the head 12 in position. l Connected to the forward end of the sliding bar 3 is a link 13 forming a connection with a bifurcated extension 111 of a pivoted lock bolt 15. This lock bolt is provided at its end with a hooked portion 16 which, when the bolt is swung downward in its locking position, engages the rear face of the keeper plate 17 enabling the lock to be employed on either a sliding or swinging door. The link 13 previously described is pivotally connected to both the sliding bar and lock bolt so as to accomplish the swinging movement just described.

Located in the upper part of the casing 1 is a latch bolt 18 slidably mounted in guides 25 and provided with a reinforcing web 19 having a spring receiving recess 20 for the reception of a spring 20 which normally holds the latch bolt in its extended position for engagement with the aperture provided in the keeper plate 17. A spindle 21 is provided on which the door knobs, not shown, are mounted. This spindle is provided with a head 22 and an arm 23 extending therefrom. A link 24 is pivotally connected to the arm 23 and the rear portiony of the latch bolt 18 so that upon operation of the spindle the bolt will be withdrawn from the aperture in the keeper plate. 1t will be noted that the link does not at any time assume a dead center, but is always at an angle to the longitudinal axis of the latch bolt so as to allow the bolt to have free movement back and forth.

In Fig. 7 1 have shown a fragment of a tumbler 26 which may be used instead of the tumbler 6 necessitating the use of a different key. rlhe configuration of the tumblers may be varied where it is desired to use different locks,

is'provided with :recesses 34 for the reception of a key by which the bolts are shifted. Slightly in advance of the recesses 34 are similar recesses 35 for the reception of the extension 9 formed on the head.12 which is carried by the operating knob l()y clearly shown in Figs. 8 and 9.

The bolt 29 is formed with a hooked end 36 which provides a socket 37 for the reception of an extension 38 provided on the keeper 39. This keeper is pivotally mounted in a casing 40 and is provided with a downwardly extending arm 41 which is engaged by the hook 36 of the bolt 29 so as to rotate the keeper and cause the extension 38 to pass into the pocket 37. Bolt 30 is provided with a. projecting lug 42 to lock the keeper from rotation and like the mem ber 29is provided with sweeps 34 and 35, at the terminal of thesweep there being however a nose 41, and it is also provided with recesses 3l and a slot 45 corresponding to those in member 29.

In operating the lock the bolt 30 is initially moved bythe extension 9 coming in contact with the projection`41 and after y such movement remains stationary until the sliding bolt'29 has been advanced'by the extension 9 to a point where the openings` 35 in the bolts 29 and 30 register. This is accomplished by the extension 9 engaging the bolt 30 will be advanced farther due to the fact that the extension 9 will still Contact projection 4l on bolt 30. rllhis latter movement causes the extension. 42 of the bolt'30 to enter an opening 43 in the keeper which' prevents the keeper from rotating lformed on the bolt 30.

until the bolt 30 is again disengaged. The

same movement yand operation Vof the bolts can be accomplished by inserting the proper Slots 45 are provided in thebolts for the reception of a stop 46 Vwhich limits the movement of the bolt so as to only rota-te the keeper a part of a revolution to bring the aperture or opening 43 in the proper position for the reception of the extension 42 For compactness of construction the -bolt lIlhe foregoing `description andthe drawings have reference to what may be considered the preferred, or approved, form of invention. It is to be understood that I may make such changes in construction and arrangement and'combination of parts, materials, dimensions, etc., as may proveexpedient and fall within the scope vof the appended claim.

Having fully described my invention what 'I claim as new and desire to secure by Letters Patent is: Y

A lock comprising aV keeper, aV housing,a latch pivotally mounted within the housing and adapted to engage the keeper, a sliding bar for operating the latch, a knob provided with a cam, means forvadvancing and rctracting the bar upon the turning ofthe knob and means for advancing and retract# ing the bar by a key, said means including a plurality of alined sweeps on the bar, the

cam cooperating with one sweep and the key with another, and a detent4 provided with `a pair of cam surfaces for cooperation respectively with the handle cam and the key.

i In testimony whereof I affix my signature 1n presence of two witnesses.V
